To solve this problem, let's set up a proportion, letting x represent the unknown number of gallons the faucet loses in 48 hours.
5 gallons / 20 hours = x gallons / 48 hours
To solve this proportion, we are going to use cross-products. This is the products of numerator of one fraction and the denominator of the other fraction set equal to one another. It results in the equation:
5 * 48 = 20 * x
Next we simplify by performing the operations.
240 = 20x
Finally, we divide both sides by 20 to get x alone on the right side of the equation.
12=x
Therefore, 12 gallons of water will be lost in 48 hours.
Answer:
50.24
Step-by-step explanation:
8÷2 is the radius. 3.14×4^2=50.24 m^2
^= where the exponent is supposed to go
Pythagorean theorem: a^2 + b^2 = c^2
a^2 + 16^2 = 65^2
a^2 + 256 = 4225
a^2 = 3969
a = 63
Perimeter: add all sides
63 + 16 + 65 = 144
Solution: 144 feet
